Monterrey had been considered a potential destination for Nicolás Fonseca; however, the club did not formally move forward with the negotiations. Instead, León de México successfully completed the deal by acquiring 60 percent of his transfer rights from River Plate for just over 2 million dollars. Fonseca's transfer to León was concluded rapidly within 24 hours, marking it as the first sale in the transfer market for River Plate. It is anticipated that the midfielder will sign a three-year contract with León, with an option to extend for an additional year.
